ABSTRACT
The purpose of this study was to evaluate the cephalometric skeletal and dental characteristics related with class II division 1 and class II division 2 malocclusions in the sagittal and vertical dimensions. Lateral cephlaograms of 100 patients for both genders were used to determine the characteristics of class II div 1 and class II div 2 malocclusion. The data base was developed in SPSS 11 for windows. In sagittal plane, mandible was more retrognathic in class II/1 than class II/2 malocclusion. Vertically, all the measurements were significantly reduced for class II div 2 malocclu-sion, indicative of a skeletal deep bite. Upper incisors were proclined in class II/1 and retroclined in class II/2 patients. Lower incisors were proclined in class II/1 while normally inclined in patients of class II/2 malocclusion. Class II/1 malocclusion is associated with more retrognathic mandible, proclined upper and lower incisors. Class II/2 malocclusion is associated with a lower anterior facial height and retroclined upper incisors
